[PATCH 00/11] sim: riscv: simulation of single and double precision floating point instructions

[<bhushan.attarde@imgtec.com>]

From: Bhushan Attarde <bhushan.attarde@imgtec.com>

Hi All,

This patch series (total 11 patches) adds simulation of riscv single and double
precision floating point instructions. This includes load-store, move, compare,
classify, sign injection, min, max, MAC, conversion and basic arithmetic
instructions. Each patch also includes tests for the corresponding instructions.

The tool-chain sources used are from:
https://github.com/riscv-collab/riscv-gnu-toolchain.git

And gdb sources are replaced with latest upstream sources from:
https://sourceware.org/git/binutils-gdb.git

GDB is configured with --target=riscv64-unknown-elf option.
